Issues with Deco BE63 3-pack working in AP mode
Just bought a 3-pack of the Deco BE63s. Setup has been a major hassle (I've wiped/reinitiated the network 6 times now).
My network setup is: Cable provider (Xfinity) coax cable from outside > structured wiring closet using Arris T25 modem (non-wireless model) > Leviton 4 port router (model #47611-GT4) > conduit that takes the CAT5E cable to various rooms in my house.
All Decos are on the same floor. The "main" deco is using ethernet cable from the wall (technically my router is "in front" of all the wall jacks); another Deco is in our home theater room wired via ethernet from the wall; the 3rd Deco is in our kitchen using wireless.
The first time I set up the Deco mesh, I used the default router mode, but soon realized that I should be using AP mode instead to benefit from ethernet backhaul, so I deleted Decos 2 & 3 using the app, unplugging them from power duringg that process, then deleted the entire network from the main Deco and started over from scratch.
Now, using AP mode on the main Deco, the 2nd Deco in my home theater room (using wired ethernet) is not showing up as being wired (in the app, there's just a straight pulsating line between the main Deco and the home theater Deco, with no ethernet cable icon as there supposedly should be).
The 3rd Deco, in the kitchen, refuses to show up at all; during setup, I'll get the yellow LED at boot, then the pulsing blue > solid blue > green, while the app says the Deco can't be found and is generally unhelpful. The Deco LED will then flash red (dropped from network), then eventually green (found network).
The app still doesn't register the 3rd Deco.
I've tried to set up this network 6 times now, and it's always the same. Extremely frustrating.
My network setup can't be changed: my house is hard wired, with a structured wiring closet, and I'm not going to abandon all the work I put into that just because TPLink thinks that their units should be the first point of contact after my modem.
If I'd known that these were so finicky, I'd have gone with another company, or stuck with my old Apple Airport Extreme towers, which have worked flawlessly for over 10 years now (I just wanted a bit more coverage, FFS).
Any help will be appreciated, or I'm probably going to RMA these and look elsewhere.
